Almost all countries exchange with one another, partly native and partly foreign goods That country, however, in whose cargoes there is the greatest proportion of native, and the least of foreign goods, will always be the principal gainer.

几乎所有国家都相互交换，部分是本国货物，部分是外国货物。然而，货物中本国货物比例最大，外国货物比例最小的国家将永远是主要的获利者。
